...Aikido is a methodology to teach principles. These principles are universal and apply to MMA, BJJ, and any other thing you do, even picking up a heavy box...

I would agree. The instructor appeared to be proficient, but the reaction from uke was very exagerated. I suspect that the instructor is actually quite good, but that his students are effectively seeing the finger pointing at the moon instead of the moon i.e. I believe what the instructor is saying as regards the principles, but there is an overtly psychadelic/flowery aspect to the training which I believe not only to be unecessary, but also misleading and diverting away from the practical application.

I believe this video does not represent the simple, direct, effective blending technique which lays at the core of aikido. Also, the psychological tricks you could use on students are extremely different to the psychological tricks you would be able to use in real attacks.
